" To whom; concern:

' my Patent' No. 804,985, date Be it known that I, 'ELBERTH. SEAnI im'a citizen of the United States, residingat Springfield, in the county of Hampden and a -State of Massachusetts, have invented certain newand useful Improvements in Firearms, "of which the following is aspecificflv I nal section. Fig. 4 is across sectioned? tion.

This invention. relates to automatic breech I loading-firearms of that tygie disclosed in 1905 andin my co-pending' application embodying improvements thereon, Serial No.

' 370,338, dated April 25; 1907. These typesof'gun are distinguishedin that the inertia "ofthe projectile, or its resistance to rotation by the rifiing in'its passage through the bar- 1 re], 'is utilized towithhol-d the. breech bolt; 1 from'recoil until the projectile has left the barrel when'through the residual. gases in the barrel the recoilof the breech bolt occurs and automaticallj operates means for ex- Pelling the spent cartridges, chargin and cocking th a L v g V My presentinvention relates .to further I improvements in certain details-of the gun mechanism adapted t'ofiineet-Tthepartlcular needs'required'of special 'service wherein the gun is usedJz-To these ends novel means are provided for the ejection: of the spent cart-ri'dges at the top of the gun; and to accomplish which, the means for holding the'barrel against rotation is disposed forvv'ardlj of the shell ejectoropening; the shell extractor 35.

determines by its position-whether or not thepiece is loaded, and with the rearv sight ing piece with which it is connected,-provides means for holding the breech plug in -pos'ition.' And a further improvement is in providing means on the gun handle for controlling thesear locking means, WhlCh COI1- A trolling meansisnormally-efi'ected and is adapted to be automatically released when the gun is gripped for firing. The sear con- .trolling means further provides a 'lockto prevent'accidental cocking'of the 'firi'ng pin.

The present invention is turthendistinct in that the device which anchors thebarrel to the gun frame affords ameans which causes counter-re'coiling movement in the gun barrel when rotating to unlock.

r Referring more in detail to the severalfigures,, wherein like reference characters indicate corresponding partsin the-differ;-

ent'views sho'wn, the numeral 1 indicates the fr'a-me of the portionit; The frame 1 ha san'extended portion 5 to which the barrel 2 is'secure'd against recoil relative thereto the securing gun, 2' the barrel therefor and 3 the breech bolt having'the extended sleeve means therefor comprises a recess 7 and an undercut portion formed in .the frame extension 5, and a lug 6 with a shoulder 6" formed on. the barrel 2, said. lug. being formed fintgral with the barrel at -its rear and under side/f- The'lug 6 and recess 7 are I disposed diagon'allyjto the axis of the gun barrel, for apurpose to be hereinafterexplain d. I T

The breech bolt 3 is of substantially that structure disclosed in my application ab'ove -referredto, and has the,usualundercut-portion andis provided with projecting inembers 13 adapted to slidingly fit within corresponding ways on the frame; -(See Fig.

:4.) The breech bolt has its shell ejection I opening 12 disposed directly above the firling chamber, the purpose whereof is to adapt the gun to be used for company firing I wherein the ejected shells will not interfere with whom ever may be next to the person firing-the gun. The barrel 2 has a lug 9 formed thereon intermediate its ends and disposed in advance of the opening12 of the breech bdlt, said member 9 providing a cam surface cotiperating with a similar surface 9 and a slotted way 10 inthe breech bolt extension 4 whereby to hold the breech bolt} against rotary movementuntil the'projectile has left-the barrel whence it permits the recoil of the breech bolt in substantially that manner described in my co-pending application, and in the patent referred to. In its rotating movement to unlock the barrel is given a counter-recoding movement by reason of the connection between the barrel and gun frame, viz. 6 and 7.

The structure of the trigger mechanism and its immediately associated. parts is substantially that disclosed in my pending application and need not therefore be described here. The breech bolt plug 3 is likewise of the structure shown in the pending case differing only in thati't has on its upper surface and running substantially the length thereof a1 groove or slot .18 to accommodate. the shell extractor and cartridge the rear sight 15-by a resilient member 14,

'which' member has slight vertical movement within the groove 18. That end of the shell extractor 17 within the firing chamber has a beveled surface 19 adapted to contact with indicator 17. Said shell -extractor and cartridgeindicator 17 has connection with a complementary surface 20 on the. rear end of the barrel whereby to provide a-close and even fit when the breech is closed. Thelower end of the piece 17. projects slightly into the recess provided for the flange on I the cartridge; shell and in such position engages the shell of the spent cart-ridge on the recoil of the breech and withdraws the same .when it is ejected in a mannerthat will be obvious. The member 17 serves to indicate whether or not the piece is loaded by its relatively projecting position above the breech bolt; thus when a shell is in position said member 17 is engaged thereby and consequently projects fart-her beyond said breech boltthan when the chamber is empty in which latter case no obstacle is offered to the normal position of the extractor. The

channel 24 formed-inthe underside of the bolt plug 3 provides thenecessary clearance for the shell ejector 39.

The structure of the'sear 11 is substantially that shown in my guns heretofore mentioned excepting that the sear arm 29 has a recess 28 cut therein and a ledge 28 which latterelement coiperate'swith a member 26' on the sear lock 21 to hold-the percussion pin in cocked position untilthe gun is gripped for firing.

The scar lock 21 has a stud22 intermediate its ends and is pivotally mounted thereon within a ,bearing 24 formed withinthe under side of the breech bolt plug whereby said sear lockv maybe moved into and out .of position to dog the sear. To effect this engagement the sear lock member 26 is adapted to move nto and out of the recess '28, which movement it has when the. gun is member 25 which cam coiiperateswith the sear lock controlling means that efi'ects the release of the same when the gun is gripped for firing. I

The safety lock or sear release controlling means comprises a plate or slide 30 mounted in an upright position in the frame land berin which'posit'ion said slide is adapted to have slight vertical movement. EAt itsiup gagement with the cam surface 25 of the searlock when the breech is closed and when such engagement is efl'ected the lug 26 of the sear lock 21 engages with the ledge 28 of the sear arm and prevents movement of said arm at all times except when the gun is gripped for firing. To

, normally keep the-safety slide 30 in contact with the sear. lock 21 and hold said lock in effective position, said slide is provided with an integral and ofi'standing shoulderv 32 against which seats a spiral spring- 34 that lies within a chamber 33 on a fixed part of the gun frame.

'Forautomatically releasing the sear lock,

the gun has a gripping lever 35 fulcrumed on a pin 36 on the rear and uppermost poi".- t'ion of the gun handle which grip has a member 39 whose design is substantially that of the contour of the handle. At

point opposite its fulcrum the lever 35 has a latch member 37 engaging within the plate 30 of a slot 38 formed in said plate. The
